Description

HTTPLogAccessOption is a bitmask that determines which fields the HTTP access log contains. Typically, this controls whether the classic Common Log Format (CLF), the Combined format with Referer / User-Agent, or additional fields such as request headers or cookies are written. This makes it possible to format logs in a way targeted at SIEM / reporting tools.

Example configuration

HTTPLogAccessOption=3

Notes & pitfalls

  • The exact meaning of the values is version- and platform-specific – look them up in the notes.ini Reference before production use.
  • Changes require an HTTP restart (tell http restart).
  • Logging cookies and auth headers can touch compliance / privacy topics – enable only selectively.
  • Pairs with HTTPLog_QueueDepth (queue) and HTTPLogAccessExclude (pattern exclusion).
